Title: Light impulse coincidence detecting
IPC: G02F1/35
Filed: 1967-09-06
Abstract: 1,148,854. Detecting coincidence of light pulses photo-electrically. TURLABOR A. G. Sept. 6, 1967 [Sept. 7, 1966], No.40721/67. Heading G1A. [Also in Divisions G2 and H1] Coincidence of two light pulses of the same frequency is detected by passing them with mutually perpendicular planes of polarization into a birefringent crystal at such an angle that one pulse is an ordinary ray and the light output from the crystal includes a component at twice the said frequency when the pulses coincide. In an embodiment for measuring the duration of pulses of wavelength 10, 600A from a laser 1, the pulses are split by a semi-transparent mirror 14 and pass through Glan- Thompson prisms 15, 17 to mirrors 16, 18. The pulses returning to mirror 14 are mutually perpendicularly polarized and pass along a common axis to a crystal 19 of potassium or ammonium dihydrogen phosphate. If the pulses coincide in time, the 5, 300A light produced by the crystal passes through a green filter 20 to a photomultiplier 21 whose output is displayed on a cathode-ray oscillograph 5. The duration of the pulses may be derived from the distance that mirror 16 has to be moved to change the output of photo-multiplier 21 from maximum to minimum. The invention may be used to measure movements of mirror 16 by counting coincidences appearing on the oscillograph 5. It may also be used in computers using light pulses. The laser 1 comprises a neodymium rod 6 between reflectors 7, 8 pumped by a flash lamp 10 fed by a capacitor discharge device 11. An amplitude modulator 9 of liquid which has low transparency at low light levels and high transparency at high light level is provided, whereby many pulses of picosecond duration and manosecond spacing are produced during each pumping flash. A filter 13 prevents radiation reflected from the device 3 reacting on the laser.

Abstract: 1277401 Dredgers P C LONDON 22 Aug 1969 [26 Aug 1968] 40724/68 Heading E1F [Also in Division G1] A dredger H having a spoil pick-up cutter head K carried by a pivoted ladder L, and a spud S providing a vertical axis about which the dredger can swing, has apparatus which continuously indicates the position of the cutter relative to a channel to be cut by the cutter. The apparatus comprises a light spot projector 10 which is moved relative to a chart, Fig. 2 (not shown), in dependence upon the operation of Selsyn receivers 64, 112 and 108 by signals received from Selsyn transmitters respectively associated with a cable drum used to move the ladder L and therefore having a rotation proportional to the angle of the ladder, a drive for moving the spud longitudinally of the dredger and therefore having a rotation proportional to the horizontal distance between the ladder pivot P and the spud S, and means driven by a gyro compass and therefore being proportional to the angle of the dredger axis with the longitudinal centre line of the channel, and upon the operation of a motor 82 controlled by manual operation of a knob for compensating for differences in the water level. The dredger may have two spuds used alternatively, and the spuds may be fixed on the dredger or may be movable to extend at an angle to the vertical. Instead of a light spot being moved mechanically to show the position of the cutter it may be shown using conventional analogue computing and electronic display techniques.

Title: Nuclear breeder reactors and nuclear reactor breeder fuel elements
IPC: G21C3/322
Filed: 1973-08-30
Abstract: 1431959 Fuel elements SIEMENS AG 30 Aug 1973 [31 Aug 1972] 40965/73 Heading G6C A breeder reactor core has a passageway therethrough for conveying coolant fluid and comprising a throttle member which resists passage of coolant fluid through the core but which undergoes a permanent change of form if the coolant temperature exceeds a predetermined value to free the passageway, so reducing the resistance to passage of coolant fluid through the core and consequently increasing the rate of heat removal. In the particular embodiment described, the upper end of a breeder element 4 is inserted with packings 8 into a tube 9 forming part of a support grid 6 and through which a gaseous coolant, e.g. CO 2  or He, is supplied in the direction of the arrows 10. The gas inflow can be varied by means of an adjustable throttle 12 having a constriction 16. The position of a displaceable throttle member 13 is adjusted relative to the constriction 16 by means of a drive (not shown) and an actuating rod 18. The adjustable throttle 12 serves for temperature regulation. A supplementary throttle 19 provided at the outflow or lower end 20 of the breeder element 4 comprises a conical plate member 21 made for example from brass having a m.p. of 900‹ C. If, in the event of considerable overheating after shutdown such as may occur with coolant pump failure or a leak, the gas temperature finally reaches the melting temperature of the material of the member 21, then this member is pressed aside or drips down under gravity, so that the entire internal cross-section of the lower end 20 of the breeder element is available for gas outflow. Thereby, the gas throughput in the direction of the arrows 22 is increased for the breeder element, so that on the reactor being shut down thermal overloading of the fuel rod encasing tubes, due to the higher degree of after-decay heat determining local temperature, is prevented.

Filed: 1971-09-08
Abstract: 1330385 Data processing KERNFORSCHUNG mbH GES FUR 8 Sept 1971 [23 Sept 1970] 41845/71 Heading G4A The invention relates to the organization of the virtual memory store of a time sharing computer. Data pages of the store are grouped into "segments" and the segments are grouped into "banks". Each bank comprises the same number of pages so that any page can be addressed by a fixed length address word b + s + p. The segments each receive a complete programme and form logically closed protected areas of the store; since programmes vary, most segments would be incompletely filled if they were all the same size. In the invention therefore the two portions s, p of the address word which identify the segments and pages are dependently variable from bank to bank, so that, for instance, one bank may have few segments of many pages for large programmes while another may have many segments for small programmes. The segment size is fixed for a particular bank and is determined by a decoder E which receives the bank address word b and instructions from a command mechanism B of the computer and presets the position of a boundary "g" between the parts s and p of the address word.

Abstract: 949,324. Automatic exchange systems. SIEMENS & HALSKE A.G. Dec. 14, 1960 [Dec. 15, 1959], No. 43117/60. Heading H4K. In a marker-controlled system using coordinate switches (e.g. relay switches, cross-bar or crossed coil selectors), interstage links or links incoming from an operator are provided with registers which store sufficient digital information to permit an operator to set up a trunk-offer call, when on first attempt at set-up the called subscriber proves to be busy. Figs. 1, 2 illustrate possible alternative positions for the additional registers 1Vn . . . 4Vn, 5V, a call being set up from an operator F via group selectors W and a final selector LW, the call being diverted to the operator if a trunk dialling subscriber Tab finds the wanted subscriber Tan busy. In Fig. 1 each register is permanently associated with an interstage link and stores only those digits necessary for setting the final stage LW. The operator first attempts to set up the call, the registers operating as described above. She then receives busy tone, but the connection is maintained up to the input of the final selector LW and in response to the busy condition the relevant information in the marker is passed to the register and the marker released. The operator then sends a trunk offer signal which causes the marker M to be seized again, and to set up a trunk-offer call provided the subscriber Tan is engaged in a local call only (different busy potentials being provided for " local busy " and " trunk busy "). The marker then receives the digits stored in the register and uses them to set the final selector LW in the case of a " local busy " subscriber. The trunk offer signal may be the dialling of the additional digit 1 which may be only effective if accompanied by a further special signal indicating that the call is from an operator. The registers may have a common access circuit such as U which is used to translate the digits into a code more suitable for storage and which the marker may more readily utilize. In Fig. 2, the registers may be fewer in number than the links and taken into use as required. With the registers shown in the position 4Vn, the register operates as previously described. The registers may instead be in the position 3Vn in front of the final selector LW. Also it is possible to use a common apparatus zu for allocating and introducing the information into one of a set of registers indicated collectively at 5V. In these circumstances it is also necessary to store the identity of the link with which the register is associated. Clearance of the registers depends on the type of arrangement. Thus in Fig. 2 the registers may be cleared when the links are released. In the case of Fig. 4 the registers are cleared immediately the information is read out on setting up the trunk offer connection. Clearance after time-out is also provided for in case no trunk offer connection is set up.
